Atrial septal defect (ASD) is a heart defect that is present at birth (congenital). As a baby develops in the womb, a wall (called the interatrial septum) forms that divides the upper chamber into a left and right atrium. An abnormal formation of this wall can result in a hole that remains after birth.This defect allows oxygen-rich blood to leak into the oxygen-poor blood chambers in the heart. The septum is a wall that separates the heart's left and right sides.
Forty-four children underwent surgery at a mean age of 8.1 ± 4.7 years (median, 6.5 years; range, 2.3–16.9 years), and 47 underwent Amplatzer occluder implantation at a mean age of 10.1 ± 4.9 years. No death occurred in either group. The mean hospital stay in the surgically treated children was 7.5 ± 3.1 daysdays versus 2.2 ± 1.1 days in the device group (P <0.001). The closure rate at discharge was similar between groups: 42 of 44 (95.5%) in the surgical group versus 46 of 47 (97.9%) in the device group.
There are no known medications that can repair the hole. Surgery may also be recommended for an adult who has many or severe symptoms. Surgery involves fixing the hole and may be done through cardiac catheterization or open-heart surgery. After surgery, follow-up care will depend on the size of the defect, person’s age, and whether the person has oTreatment ther birth defects.
